Final answer:
If a driver has high beams on, look toward the right edge of your lane, using the white line as a guide, and avoid looking directly at the bright lights to maintain visibility and safety.
Step-by-step explanation:
When encountering a driver with high beams on, it is important not to look directly at the lights as it can impair your vision. Instead, you should look toward the right edge of your lane and use the white line as a guide until the other car has passed.
This will help to avoid being temporarily blinded by the bright light and maintain your visibility of the road. It's also a good practice to slow down and increase your following distance to ensure safety if you're having trouble seeing.
